- You’re listening to “The implementation of artificial intelligence in organizations by functional areas: A review and conceptual model,” by Juan-Manuel Aguado-García, Sara Alonso-Muñoz, and Carmen De-Pablos-Heredero. Published in Journal of Management & Organization in July 2026. Abstract. The rapid expansion of artificial intelligence has accelerated its adoption across organizational functions. However, existing reviews often adopt sectoral or technology-focused perspectives, limiting understanding of its implementation within core firm activities. This study addresses this gap through a systematic review of articles published in Web of Science and Scopus up to December 2025, following established methodological guidelines. A total of 160 peer-reviewed articles met the inclusion criteria. Findings reveal convergent patterns of adoption in human resources, marketing and customer services, logistics, and finance. Artificial intelligence enhances analytics, automates routine tasks, personalizes interactions, and supports decision-making. Human resources applications focus on recruitment and workforce planning; marketing relies on predictive analytics and conversational interfaces; logistics improvesforecasting and supplychain resilience; finance strengthens risk assessment and process efficiency. The study proposes an integrative conceptual model and research propositions, highlighting cross-functional challenges in governance, organizational capabilities, socio-technical alignment, and responsible implementation. Introduction. The growing significance of artificial intelligence (AI) in society is irrefutable. While AI is currently in its infancy in the business realm, it is a phenomenon that merits attention. A report by the World Economic Forum estimates that the use of AI in economic activities will result in the destruction of 75 million jobs, while simultaneously generating 133 million new jobs. In this new AI-driven paradigm, there is a clear requirement for several specific profiles, including data analysts, designers, critical thinkers, software engineers, AI engineers, digital marketers, remote managers, software analysts and developers, cybersecurity professionals, digitization lawyers, web analysts/CROs, social media experts, and many others. While it is accurate to assert that companies prioritize analysis and optimization of processes, which are conceptualized as sequences of tasks from initiation to completion, the prevailing organizational structure in business practice is characterized by the establishment of distinct departments, each specialized in a specific function. It is evident that a wide range of departments will be involved in this transformation towards a new paradigm. At the strategic level, the ability to sense, seize, and reconfigure resources in response to digi-tally enabled opportunities is consistent with Dynamic Capabilities Theory. At the functional level, organizations operationalize strategy through differentiated units that coordinate specialized capabilities, and recent work suggests that AI systems reconfigure these coordination architectures by reallocating cognitive and analytical tasks across organizational functions. These mechanisms collectively underpin organizational learning processes, which are central to understanding how AI-enabled capabilities become embedded in organizational routines. Moreover, the implementation of AI technologies necessitates the alignment of technological artefacts, organizational structures and human actors within a socio-technical framework. At the individual level, adoption behaviours are influenced by cognitive evaluations of system usefulness and ease of use, as articulated by the Technology Acceptance Model (TAM; Davis, 1989; Venkatesh, Morris, Davis & Davis, 2003), which helps explain employee-level acceptance. All these perspectives provide a multilevel conceptual foundation for examining how AI affects organizational performance, coordination, and value creation. Reviewing AI adoption at the functional level contributes to consolidating a fragmented research domain. While prior reviews have examined AI indifferent sectors and areas, out paper expands the limited understanding of how AI diffuses across internal organizational functions. Mapping these patterns enables the articulation of mechanisms and propositions that support future theory-building on AI-enabled organizational transformation. Since most studies in this field are superficial and follow exploratory models, our work has the potential to contribute to the field of study, which currently lacks validated models and requires greater empirical robustness. Existing reviews provide the state-of-the-art focus on AI applied to a particular area, for instance, on the effects on service robots in business or AI and entrepreneurship and information systems. In management, Dhamija and Bag (2020) highlight the most influential journals and authors as well as the top keywords. While Sestino and De Mauro (2022) focus on AI value-driven applications. There are previous literature reviews in the field of organization and AI applied to sectors such as banking and marketing. A previous article had reviewed the literature on the implementation of AI in organizations. However, the preceding analysis reviewed articles up to 2021 and focused on organizations rather than on the different functional areas within the business world. Recent literature indicates a substantial surge in the implementation of AI-based chatbots within the business realm, with a predominant focus on the automation of customer service, the enhancement of user experience, and the integration of natural language processing technologies. This period of accelerated growth has been particularly evident since 2021, when tools such as large language models (e.g., GPT) began to gain popularity and dis-seminate among companies in multiple sectors seeking to optimize their operations and customer relationships. Table 1 summarizes most outstanding findings from literature review. In fact, Duan, Edwards and Dwivedi (2019) highlight the scarcity of theoretical frameworks to comprehend the use of AI and how they impact organizations. Consequently, understanding how AI is being adopted in departments such as HR, marketing, logistics, and finance provides actionable guidance for decision-makers responsible for functional deployment, resource allocation, and capability development. Therefore, to analyse the current work being carried out and the way the new AI tools are being implemented is required. The aim of this paper is to investigate the literature focusing on how the organizations are imple-menting AI in the different departments to identify good practices and opportunities. Considering the growing interest in AI and its application to organizations and the lack of research, to address this gap, a systematic literature review has been conducted and therefore a conceptual model has been developed. Hence, the research questions to address are the following: RQ1. How are companies approaching the use of AI-related technologies in their different departments? RQ2. What improvement needs have been detected in the different functional areas to implement AI? RQ3. How can the implementation of AI improve the functional areas in organizations? This paper will analyse the current literature in the field of AI and its application in organizations by departments for the first time. Besides, this paper will propose a conceptual model for the implementation of AI by departments that may be useful for firms to consider when applying AI to their departments. After this introduction, Section 2 describes the theoretical background, and Section 3 describes the methodology. Section 4 presents the main results, Section 5 proposes the conceptual model, and finally discussions and conclusions are provided. Theoretical background The application of AI in the business world The application of AI in human resources area In recent years, the application of AI in the field of human resources has become increasingly important, driven by the need to optimize organizational processes, improve decision-making, and increase efficiency in human capital management. In this context, organizations are incorporating systems based on machine learning and data analysis to support key functions such as work planning, performance management, training, and recruitment. One of the primary applications of AI in human resources management pertains to the operational and organizational management of staff, particularly through the utilization of tools capable of analysing substantial volumes of data to facilitate the more efficient organization of shifts, workloads, and schedules. These applications empower supervisors and department heads to optimize human resource allocation, reduce organizational inefficiencies and minimize absenteeism, thereby contributing to the creation of more stable and predictable work environments. Conversely, the utilization of automated systems for the prioritization of tasks and resources has been demonstrated to engender enhanced organizational clarity and opti-mized time management, thereby exerting a favourable influence on job stability. A further pertinent domain of application is the monitoring of the working environment, with a view to the identification of dysfunctional organizational dynamics, such as harassment or bullying in the workplace. In this regard, AI is employed to automatically analyse internal questionnaires, climate surveys, and other organizational assessment tools, enabling the identification of risk patterns and supporting preventive decision-making by human resources departments. These tools do not seek to supplant human intervention; rather, they seek to provide analytical support to enhance the quality of the work environment and to prevent poor practices in people management. The optimization of strategic human resource processes, including the reduction of operating costs, the maintenance of social dialogue and the enhancement of management skills, constitutes a prevalent application of AI in contemporary organizations. In this context, the implementation of automation for repetitive administrative tasks enables human resources professionals to focus their efforts on functions that generate greater added value, such as talent development and strategic planning. In the context of recruitment and selection, AI has emerged as a pivotal instrument for the management of processes characterized by a high volume of applications Martín-Hernández, 2023). Intelligent systems have been developed to automate the profile filtering process, verify the consis-tency and accuracy of CVs, and pre-select candidates based on predefined objective criteria. This process has been shown to contribute to greater efficiency and standardization. However, academic literature emphasizes the necessity for conscientious and overseen utilization of these technologies to circumvent algorithmic bias and ensure equitable decision-making. Finally, in the domain of training and skills development, AI plays an increasingly significant role in the identification and enhancement of transferable skills within organizations. These competencies enable employees to adapt to different roles and work contexts, thereby promoting organizational flexibility. The automation of routine tasks has been demonstrated to liberate working time, enabling employees to engage with more complex activities, thereby enhancing productivity and innovation. Moreover, a particularly salient emergent application of AI in training is the utilization of AI for self-learning by employees, particularly in light of the prevailing training deficit in this domain. The objective is to furnish workers with the knowledge and tools necessary to enhance their skills through the utilization of intelligent systems, encompassing virtual tutors and educational chatbots. In order to facilitate the adoption of these technologies and to reduce possible initial resistance, it is essential to provide clear and transparent information on the objectives and func-tioning of training programmes, as well as on the use of learning support models. One such model is proposed in this paper. The systematic collection of training data, its analysis, and the automation of these processes have been shown to make it possible to progressively improve the effectiveness of corporate training plans. The use of AI in marketing and customer services areas The application of AI in the field of marketing has undergone significant expansion in recent years, driven by the necessity to enhance customer understanding, personalize offerings, and optimize the quality of interaction between businesses and consumers. In this context, marketing has become one of the functional areas where AI has the most direct and visible impact, as it is integrated across data analysis, communication, recommendation, and customer service activities. It is widely acknowledged that AI applications in marketing can be categorized into three over-arching and interconnected domains. The first of these is active listening and advanced analysis of customer behaviour, which involves the real-time collection and processing of data from multiple sources, such as digital interactions, location, consumption habits, or activities recorded through sensors and smart devices, including smartphones and wearables. These capabilities enable organizations to gain a deeper and more dynamic view of the customer, thus surpassing traditional approaches based on historical data or static segmentations. The second key area is the prediction of needs and the personalization of content, products and services. The employment of machine learning algorithms facilitates the anticipation of user prefer-ences, the categorization of substantial data pertaining to tastes and behaviours, and the generation of personalized recommendations or bespoke advertising campaigns in real time. Polaris, the search engine developed by Walmart, serves as a prime example of this application type. It has been designed to help consumers identify products that align with their interests, even in the absence of explicit awareness of their needs. This innovation has the potential to enhance the overall shopping experience and enhance the perceived value of products and services. These applications serve to reinforce the strategic role of data-driven marketing and contribute to greater efficiency in the allocation of commercial resources. The third fundamental area pertains to direct interaction with the customer and relationship management throughout the life cycle, wherein AI-based systems, notably chatbots, and virtual assistants, assume a pivotal role. These systems facilitate real-time, two-way interactions, including emotional components, thereby enabling the establishment of more organic connections between the brand and the consumer, which in turn contributes to brand value enhancement. From a functional perspective, chatbots are designed to optimize communication between humans and machines, thereby streamlining customer service and reducing response times. Consequently, customer service can be regarded as a natural extension of relationship marketing, rather than a distinct discipline. The application of AI in this context is not limited to the collection of complaints or incidents; it also allows for proactive solutions aimed at improving service quality and anticipating customer needs through continuous analysis of data from devices and interaction channels. This evolution transforms customer service into a strategic source of information for marketing, feeding into other processes such as the personalization of offers, loyalty building and the design of new value propositions. Current research is also focused on improving the natural language processing capabilities of these systems, not only in terms of written language, but especially in verbal interaction, which broadens their applicability and naturalness in real service contexts. The data generated through these interactions is not only valuable for customer service but can also be extrapolated to other departments within the organization, reinforcing the cross-cutting nature of AI in business strategy. Finally, recent literature emphasizes the importance of integrating these AI applications in marketing within solid conceptual frameworks that combine empirical evidence and theoretical foundations, in order to guide professionals in their effective adoption and avoid a merely instrumental use of technology. In this sense, AI should not be understood solely as a set of tools, but as a strategic enabler that redefines the way organizations listen, interact and build valuable relationships with their customers. AI in manufacturing and logistic areas The evolution of contemporary manufacturing and logistics systems has been accompanied by the development of increasingly sophisticated technological infrastructures based on information technology (IT), smart sensors, and interconnected devices. This set of technologies is commonly referred to as a smart factory or Industry 4.0, in which AI plays a central role as an integrator of data and processes. In this context, business logistics is increasingly dependent on intelligent systems to enhance operational efficiency, supply chain coordination and the ability to adapt to changing environments. From an organizational perspective, it is essential that logistics departments accurately identify discrepancies between their operational needs, the technological resources available on the market, and the expectations of end customers. The integration of large volumes of data from multiple sources is facilitated by AI, enabling more informed decision-making that is aligned with the company’s strategic objectives. With regard to the implementation of automation in logistics operations, AI is employed in a variety of ways. These include the control and programming of robots in warehouses, the automated visual inspection of products, the early fault detection, and the predictive maintenance of logistics systems. These applications are commonly integrated with technologies such as the Internet of Things (IoT) and cyber-physical systems, enabling real-time monitoring of assets, goods flows, and operating conditions throughout the logistics chain. Consequently, process reliability is enhanced and costs associated with unanticipated interruptions or operational errors are diminished. Within the domain of supply chain management, AI is employed to analyse historical and real-time data to forecast future demand, plan resources and optimize coordination between the various links in the chain. These analytical capabilities contribute to a more efficient allocation of inven-tory, transport and production capacity, generating cost savings and greater responsiveness to market fluctuations. In addition, the utilization of predictive models facilitates the anticipation of bottlenecks and enhances the resilience of the supply chain in the face of external disruptions. In this context, generative AI emerges as a complementary tool with high strategic potential in logistics. These systems have the capacity to analyse complex scenarios related to political, social or economic changes, and to support risk assessment by generating models of possible disruptions in demand or supplier availability (Richey, Chowdhury, Davis‐Sramek, Giannakis & Dwivedi, 2023). Furthermore, generative AI has the potential to facilitate the design of more efficient distribution strategies, the optimization of logistics routes, and the analysis of external factors such as weather patterns or environmental constraints, as well as internal company needs, including cost reduction and the management of occasional increases in demand. The integration of AI into logistics is not confined to the adoption of isolated tools; rather, it involves a progressive transformation of logistics processes towards more intelligent, predictive, and adaptive models. This evolution enables organizations to improve their operational efficiency, increase supply chain visibility and strengthen their responsiveness to highly dynamic and competi-tive environments. The application of AI in finance area The digital transformation of the finance department has been driven in recent years by the incor-poration of advanced technologies such as blockchain, cloud computing, big data analytics and 5 G networks. These technologies have established the foundations for the development of digital platforms based on AI, with the primary aim of automating complex tasks, integrating information from multiple sources and improving operational efficiency in financial management. In this context, AI functions as a pivotal component, facilitating the dynamic coordination and analysis of substantial financial data in real time. One of the primary applications of AI in the financial sector pertains to the automation and optimization of internal management processes. AI-based platforms facilitate real-time analysis of tasks such as budget comparison, alert generation, deviation monitoring, and accounting process execution. Consequently, technologies such as image and voice recognition have been employed to automate document and accounting management, thereby reducing human error and enhancing the efficiency of financial processes. The relevance of these applications is especially pronounced in complex organizational environments, where the speed and accuracy of financial decision-making are critical factors. Another line of application that has been extensively documented in the literature is the use of AI in the development of innovative financial services and digital banking solutions. In this domain, AI is employed to enhance the customer experience by means of the automated provision of personalized products and services, which are based on the analysis of financial and consumer behaviour. Furthermore, these technologies facilitate the processing and analysis of substantial volumes of data generated by users themselves, including data from personal devices. The objective of this is to anticipate needs, optimize customer interaction and improve commercial efficiency. Concurrently, the realm of financial transactions is a pivotal domain in which AI is being integrated with other emerging technologies, such as blockchain and the Internet of Things (IoT). The adoption of blockchain technology has seen a marked increase in sectors such as healthcare, retail, manufacturing, and financial services, due to its ability to guarantee data integrity and process transparency. When combined with AI-based systems, this technology facilitates the automation of financial operations, streamlining transaction approvals and managing large volumes of operations securely, through advanced recording and control mechanisms. Despite the proliferation of AI applications in the financial sector, extant literature tends to address these technologies in a fragmented manner, focusing on specific tools or use cases, without offering integrative frameworks that explain how these solutions can be coherently aligned with financial management processes and strategic decision-making. Furthermore, there are still significant gaps in relation to the criteria for the effective adoption of these technologies, their organizational impact and their integration with existing management models. These limitations underscore the necessity for research that systematically analyses the role of AI in the finance department and provides a basis for the research questions raised in this paper, thus contributing to a more structured and efficient use of AI in corporate financial management. Methodology. This article applies an exploratory and conceptual investigation to examine the implementation of AI technologies in different departments at organizations. Systematic and structured literature review was applied for the first time in the medicine research area; however, its use has been extended to other fields such as management. A systematic literature review is employed to this study to synthetize findings from a prior body of research in a reproducible, transparent, and systematized manner, and the data are collected, assessed, and identified provid-ing scientific rigour. Hence, systematic reviews provide defensible findings. The aim is to recognize and detail pre-established criteria to reach reliable results to inform and draw conclusions about the current literature to address the research questions suggested. The methodological approach adopted in this study was consistent with the methods reported in the academic literature. Specifically, the systematic review was structured using PRISMA statement (Preferred Reporting Items for Systematic Reviews and Meta-analyses), as illustrated in Fig. 1, widely used in previous analyses. While CASP was employed for the critical assessment of the methodological quality of the included studies. The sample was retrieved from Web of Science (WoS) and Scopus databases. The bibliometric analysis was conducted using WoS and Scopus, which are recognized as the two leading multidis-ciplinary citation databases for scientific mapping and performance analysis due to their rigorous indexing processes and structured citation data. The search query prioritized AI-related technologies combined with organizational umbrella terms. Function-specific terminol-ogy (e.g. ‘people analytics’, ‘supply chain’, and ‘HR’) was intentionally excluded from the Boolean chain to prevent the search from being biased towards particular functions, and to enable the databases’ controlled vocabulary and indexing to retrieve publications related to functional domains via the title, abstract, or keyword fields. This approach is consistent with PRISMA guidelines and prior reviews in management and information systems. It is important to note that the exclusion of functional terms from the query does not imply the exclusion of research in such domains. During the coding and classification stages of the review, several functional areas emerged in the dataset, including human resources (e.g. recruitment, training, and people analytics), logistics and supply chain management, marketing/customer services and financial services, which are repre-sented in the final sample. Consequently, these domains were captured empirically through screening rather than through query formulation. The review focused on literature situated within the organizational and management domains. While interdisciplinary publications were not excluded a priori, studies from neighbouring fields (e.g. healthcare, education, the military, and engineering) were excluded if they lacked an explicit organizational or functional application of AI. This approach ensures that the evidence base aligns with the research questions and avoids conceptual dispersion. In accordance with the PRISMA guidelines (Moher et al., 2010, explicit inclusion and exclusion criteria were defined. The following inclusion criteria are to be observed: firstly, peer-reviewed journal articles; secondly, studies examining the implementation or use of AI within organizational settings; thirdly, studies addressing organizational functions, practices or activities; and fourthly, articles written only in English. The exclusion criteria exclude conference papers, book chapters, theses and non-peer-reviewed publications (denominated grey literature), studies situated in non-organizational domains (e.g., healthcare diagnostics, autonomous robotics, military, education), studies focusing on technical or algorithmic development without organizational implications, theoretical or ethical essays without applied organizational relevance, and publications unavailable in full text or written in languages other than English. Therefore, the search query used, based on previous reviews was sorted by title, abstract and keywords, using the following terms in both database: (‘Artificial Intelligence’ OR ‘AI’ OR ‘Machine Learning’ OR ‘ML’ OR ‘Deep Learning’ OR ‘Robotics’ OR ‘Neural Networks’ OR ‘Data Learning’ OR ‘Expert Systems’ OR ‘Intelligence Interfaces’) AND TS = (‘organization’ OR ‘organization’ OR ‘firm’ OR ‘enterprise’ OR ‘compan’ OR ‘corporation’) AND TS = (Department OR ‘function area’). Considering articles between 1988 – when the first article appears – up to December 2025. Table 2 summarizes the inclusion and exclusion criteria applied during the screening and eligibility phases. The criteria were defined ex ante, consistent with PRISMA 2020 guidelines, and reflect both conceptual and methodological alignment with the research objectives. The results obtained were 1,219 in WoS and 3,590 in Scopus. Therefore, both bases were filtered to focus only on Social Sciences studies and to consider only articles, collecting a final sample of 178 and 381, respectively. Two of the authors have reviewed all the articles’ abstracts (and in case of doubt the whole manuscript) to check if they met the aim of the study. Subsequent to the removal of duplicates, 399 publications were excluded during the screening phase. The primary reasons for exclusion were that 128 studies focused on non-organizational domains, pre-dominantly healthcare, American Indians, military contexts and standalone robotics; 122 studies centred on technical AI development without organizational application; 72 publications addressed ethical, societal or philosophical perspectives rather than functional implementation; and 23 studies were excluded due to full-text unavailability or non-English language. The selection criteria ensured that the finalized dataset comprised studies that were aligned with the aim of review-ing how AI is being implemented within organizational functional areas. Hence, the final sample considering both databases is 160. In order to evaluate the credibility and transparency of the included evidence, a structured quality appraisal protocol based on the Critical Appraisal Skills Programme (CASP) was applied to all retained studies (N = 160), adapted from CASP (2019) and Zunder (2021). The checklist encom-passed nine criteria, which were grouped into the following dimensions: screening, validity, and contribution. These criteria encompassed the assessment of clarity of aims, methodological reporting, conceptual elaboration, empirical grounding, and practical relevance. Responses were categorized as ‘Yes’, ‘No’, or ‘Can’t tell’ (see Table 3). Percentages represent the proportion of studies meeting each criterion over the full corpus. In order to enhance the rigour and reliability of the quality appraisal process, the CASP checklist was applied independently by two authors. Productivity measures The first article about this research domain was published in 1997 in the Journal of the Operational Research Society. This study focused on predictions for the insurance sector thanks to neural networks. As can be seen in Fig. 2, which shows the historical evolution of the research field in AI and departments’ organization, there has been a notable increase in the number of articles published since 2019, coinciding with the Covid-19 pandemic, that boosted the use of these technologies, particularly in medical areas. Although in the year 2021 there is a slight decrease. It is during these 5 years (2020–2025) that the 86.25% of the scientific production is concentrated, specifically during 2024 and 2025 with a proportion of more than half (51.25%). Another aspect to highlight is how the emergence of tools such as chatbots have been able to boost studies related to this topic. For instance, ChatGPT, launched in 2022. However, it should be noted that only articles published up to December 2025 have been considered in this analysis. Regarding the topmost influential journals (Table 4), the most productive and cited journal is Sustainability, with 12 published documents and 177 total citations, followed by Government Information Quarterly and International Journal of Environmental Research and Public Health. Referring to the research areas, these journals are mostly multidisciplinary, highlighting those related to environmental science and studies, health, information, and computing science. What is noteworthy is that journals related to the area of management are not the most prominent, even though the subject of study is fully focused on business (Social Science Citation Index). The quality appraisal was conducted using an adapted CASP protocol applied to the full corpus (N = 160). The results of the study indicate that the majority of the studies addressed a clearly focused issue (94.38%) and explicitly stated their research aims (92.50%). The screening process demonstrated a high level of relevance, with 95.00% of the studies being pertinent to the review questions. Conversely, the reporting of methodological procedures was more heterogeneous. While 68.75% of the studies provided a clear explanation of their research methods, only 53.13% adequately described the procedures used for data collection. Conversely, conceptual elaboration (77.50%), practical relevance (88.75%), and theoretical contribution (84.38%) exhibited notably higher scores. Further analysis revealed that the screening exhibited a high level of clarity (90.28% Yes) and a Source: own elaboration based on CASP (2019) and Zunder (2021). robust contribution profile (82.65% Yes), while concurrently demonstrating comparatively lower methodological transparency (66.46% Yes). The primary results for each of the designated functional areas are presented in Table 5, accompa-nied by proposed future research directions. A quantitative analysis of the data presented in Table 5 indicates that the areas of the organization that accumulate the greatest number of papers are, in descending order of magnitude, human resources (35.62%), marketing and customer services (25.62%), and operations (21.87%). AI implementation per departments: A conceptual model The advent of AI has been closely associated with operational and strategic departments, with the decision support system (DSS) serving as a pivotal element in its initial implementation. This has subsequently extended to encompass the rest of the organizational structure, with the DSS acting as a direct conduit between the various departments. The quality appraisal was conducted using an adapted CASP protocol applied to the full corpus (N = 160). Abbreviations: JCR = Journal Citation Report; D = Total documents; TC = Total number of citations. The results of the study indicate that the majority of the studies addressed a clearly focused issue (94.38%) and explicitly stated their research aims (92.50%). The screening process demonstrated a high level of relevance, with 95.00% of the studies being pertinent to the review questions. Conversely, the reporting of methodological procedures was more heterogeneous. While 68.75% of the studies provided a clear explanation of their research methods, only 53.13% adequately described the procedures used for data collection.

A quantitative analysis of the data presented in Table 5 indicates that the areas of the organization that accumulate the greatest number of papers are, in descending order of magnitude, human resources (35.62%), marketing and customer services (25.62%), and operations (21.87%). The conceptual model (Figure 3) proposed is based on the main contributions by functional areas (see Table 5) and, in this study, aims to consolidate dispersed evidence on AI implementation across organizational functional areas and to articulate theoretically grounded propositions for future empirical testing. The conceptual model proposed in this paper moves beyond the descriptive mapping of AI applications. The objective of this research is threefold: firstly, to integrate findings across functional areas; secondly, to identify the usage patterns underlying AI implementation; and thirdly, to formulate propositions that enable testable theoretical extensions. The model’s primary function is to consolidate a fragmented research domain, thus providing a structured baseline for scholars and practitioners to guide the adoption and future empirical validation of AI-related practices in organizations. The establishment of AI for human resources In the domain of human resources, ongoing training and the cultivation of transferable skills are identified as pivotal factors for enhancing organizational performance and fostering internal adaptability. The utilization of AI facilitates the automation and personalization of training processes, thereby enabling the monitoring of learning and the provision of continuous feedback in the absence of direct human supervision. This, in turn, enhances the effectiveness of skills development. Furthermore, the capacity of AI to analyse and map competencies at the organizational level facilitates the identification and transfer of skills between departments, thereby reinforcing internal mobility and the strategic use of human capital. It is upon this foundation that the subsequent propositions are proposed: Proposition 1 (P1). The utilization of AI systems for the automation and personalization of training has been demonstrated to be positively associated with the development of employee competencies. Proposition 2 (P2). The utilization of AI systems for the purpose of competency management has been demonstrated to be positively associated with the transfer of skills between departments within an organization. The establishment of AI in marketing and customer services is a common practice. Marketing and customer service are closely linked through their shared reliance on customer data analysis and direct interaction with end users. The integration of AI within these domains empow-ers enterprises to process substantial volumes of customer data in real time, thereby enhancing the personalization of products, services, and communications. In particular, AI-driven tools such as recommender systems and chatbots facilitate more accurate identification of customer prefer-ences, responsiveness, and emerging needs, thereby enhancing customer experience and supporting data-driven marketing strategies. It is from this reasoning that the following propositions are derived: Proposition 3 (P3). The utilization of AI in marketing and customer service is positively associated with the personalization of products and services. Proposition 4 (P4). The utilization of AI in marketing and customer service has been demonstrated to be positively associated with firms’ ability to identify customer needs and responsiveness. The establishment of AI in logistics Within the domain of logistics, AI has emerged as a pivotal catalyst for enhancing efficiency, visibil-ity, and resilience across supply chains. The integration of AI with big data analytics and real-time information systems enables firms to forecast demand, monitor inventory levels, and anticipate raw material requirements with greater precision. These capabilities support proactive decision-making, allowing organizations to optimize stockpiling strategies, reduce uncertainty, and respond more effectively to disruptions in dynamic supply chain environments. Furthermore, the utilization of AI-driven predictive analytics facilitates the identification of potential risks and bottlenecks within logistics networks, thereby enhancing coordination among supply chain partners and ensuring improved operational continuity. Consequently, logistics functions are progressively reliant on AI-based tools to enhance forecasting accuracy, whilst also fortifying supply chain resilience and adaptability in the face of market volatility and external shocks. The following propositions are advanced on the basis of this rationale: Proposition (P5). The utilization of AI in logistics has been demonstrated to be positively associated with the accuracy of demand and resource need forecasting. Proposition (P6). The utilization of AI in logistics has been demonstrated to be positively associated with supply chain resilience. The establishment of AI in financial services In the domain of financial services, the convergence of AI with enabling technologies such as blockchain, cloud computing, big data analytics, and 5 G has led to a substantial acceleration in the digital transformation of financial activities. Collectively, these technologies enhance the capacity of firms to process large volumes of transactional and customer data in real time, improve risk assessment, and automate complex financial operations with higher levels of security and transparency. In particular, AI-driven digital platforms and chatbots have become central tools for improving customer interaction, enabling the personalization of financial products and services, and supporting internal job customization through the automation of routine financial tasks. This transition enables financial departments to enhance operational efficiency while concurrently delivering more customised and responsive services to customers. It is from this rationale that the following propositions are derived: Proposition 7 (P7). The utilization of AI in the domain of financial services has been demonstrated to be concomitant with the digital transformation of online financial platforms. Proposition 8 (P8). The utilization of AI-driven chatbots in the financial services sector has been demonstrated to be associated with a positive correlation to the customization of financial products and job tasks. Discussion. The review shows that AI’s organizational implications are inherently multilevel. Strategically, AI supports sensing, opportunity identification and capability reconfiguration – mechanisms aligned with Dynamic Capabilities and the trajectories of digital transformation. Functionally, AI augments information processing and coordination across differentiated units, in line with classic views of functional specialization and coordination. Recent work further indicates that learning algorithms reallocate analytical and cognitive tasks across boundaries, reshaping coordination structures and occupations. Viewed together, these effects propagate through organizational learning processes and require socio–technical alignment between artefacts, structures and actors. At the individual level, adoption heterogeneity is well explained by TAM, perceived usefulness and ease of use remain pivotal. Overall, AI cannot be meaningfully examined in isolation: its effects unfold through interdependent strategic, functional, socio–technical and behavioural mechanisms. Prior reviews have mapped AI within specific domains, e.g., information systems, entrepreneurship and operations/management foci, as well as sectoral lenses such as banking and marketing. Our contribution differs by synthesizing findings across core organizational functions and by incorporating emerging themes, notably, the rapid dif-fusion of chatbots and AI–mediated workplace enhancements, thus offering an integrative view that connects technologies, routines and outcomes. Compared with Lee et al. (2023), who cover evidence up to 2021 and at a general organizational level, our analysis extends the time window to 2025 and develops function–specific propositions (P1–P8). Ethical, social, and regulatory concerns cut across functions. As AI adoption intensifies in HR and marketing, a pattern driven by customer–centricity (marketing) and efficiency/productivity aims (HR), responsible design and governance are essential to mitigate risks of bias, opacity and privacy harms. These concerns rein-force the need for fit–for–purpose regulatory frameworks that enable data access and sharing while safeguarding workers, customers and broader societal interests. Linking findings to the research questions and to the propositions RQ1. Adoption pattern. Across HR, marketing/customer service, logistics and finance, adoption follows a common sequence: (i) analytics and decision support, (ii) task/process automation and personalization, and (iii) cross–functional data integration as the primary enabler. This pattern coheres with recent evidence in Human Resources Managemente and development(HRM/HRD) and Supply Chain Management (SCM) and underpins P1–P8, which specify function–level outcomes and enabling conditions. RQ2. Improvement needs. Four cross–functional priorities emerge: data foundations (quality, governance, interoperability); capability building (hybrid human–AI skills); socio–technical alignment (workflow redesign, decision rights, escalation); and responsible AI (fairness, accountability, transparency). HR research articulates these constraints particularly small size phenomena, causal ambiguity and accountability/fairness, motivating experimental and causal logics in deployment; our findings embed these in P1–P2. RQ3. Performance effects and contingencies. Gains in personalization (marketing/CS), forecasting and resilience (logistics), automation and risk assessment (finance), and competence development (HR) materialize when AI is embedded in robust data pipelines, human–in–the–loop governance, and cross–functional routines, conditions reflected in P1–P8. In SCM, evidence indicates that resilience effects are phase–contingent (readiness/response vs. recovery/adaptability), refining P6 and cautioning against over–generalization. Positioning vis–à–vis the broader literature In HR/HRD, foundational work highlights four structural challenges for AI in employee management: complex HR phenomena, small–N constraints, fairness/legal accountability, and potential negative employee reactions, advocating causal reasoning and experimentation in deployment. Our results align with this stance and specify where benefits are most plausible (AI–guided learning and competency mapping/transfer), informing P1–P2. In supply chains, systematic reviews map technique adoption and promising subfields, while resilience–focused syntheses report limited, phase–skewed primary evidence. By linking P5–P6 to forecasting accuracy and phase–contingent resilience, our model integrates technique–centric mappings with disruption–management logics, setting clearer expectations for effect heterogeneity. Main contributions This review offers a structured answer to the three research questions and advances an integrative model for AI implementation across organizational functions. RQ1. How firms approach AI by function. We identify a consistent, cross–functional adoption sequence-analytics/decision support, automation/personalization, cross–functional integration, observed in HR, marketing/CS, logistics and finance, and coherent with recent systematic and bibliometric reviews in HR/HRD and SCM. RQ2. Improvement needs. Across functions, success hinges on data governance, analytic capability building, socio–technical alignment, and responsible AI. In HR, foundational work emphasizes fairness, accountability, and small–N constraints; in SCM, resilience requires better coordination and phase–aware deployment. These needs are embedded in the conditions attached to P1–P8. RQ3. Performance enhancement and conditions. AI improves functional performance when embedded in complementary assets and governance: competence development and skill transfer in HR (P1–P2), personalization and responsiveness in marketing/CS (P3–P4), forecasting accuracy and phase–contingent resilience in logistics (P5–P6), and automation and product/job customization in finance (P7–P8). These effects are conditional on robust data pipelines, human–in–the–loop oversight, and cross–functional interfaces. Contribution of the model. Beyond descriptive mappings, the conceptual model consolidates dis-persed evidence into eight testable propositions at the functional level, offering a tractable pathway for empirical validation and theory building on capabilities, coordination, and learning in AI–enabled organizations. The integration of HRM/HRD syntheses (including a PRISMA–based review) and SCM reviews (technique mappings and resilience) aligns the paper with the current frontier and frames a precise agenda for cumulative research. Following we suggest managerial takeaways by function: HR: Prioritize fairness awareness, explainable AI in personalized learning and competency mapping to unlock competence growth and internal mobility (P1–P2). Marketing/CS: Orchestrate task technology fit and transparent escalation in chatbots and recom-menders to maximize personalization and responsiveness (P3–P4). Logistics/SCM: Pair predictive analytics with phase aware resilience design and cross partner data sharing to realize gains in forecasting and resilience (P5–P6). Finance: Combine automation with explainability and controls in digital channels to deliver platform transformation and job/task customization (P7–P8). A multilevel reasoning of AI in organizations has been done. We bridge strategic (sensing/reconfiguring), functional (redistribution of analytical/cognitive tasks), socio–technical (alignment of artefacts, structures, actors), and individual (acceptance) mechanisms, embedding these links in P1–P8. Rather than a unitary–actor view of the firm, we show how functions operationalize strategy and are precisely where AI reallocates decision rights and reshapes routines (i.e., HR learning paths; CRM–driven personalization; supply–planning control towers), motivating function–specific hypothesis tests under a shared multilevel scaffold. Positive outcomes hinge on bundles of data governance + analytic literacy + cross–functional teaming and on architectures that govern how predictions flow into interdependent decisions, shifting the debate from ‘tools’ to organizational design. Efficiency and bias–mitigation claims coexist with concerns over fairness and negative employee reactions, especially under opacity/surveillance. Benefits surface where organizations adopt experimentation/causal logic, transparent criteria and human–in–the–loop oversight, conditions consid-ered in P1–P2. General SCM reviews suggest improvements, yet resilience–specific syntheses remain limited and phase–skewed; P6 therefore predicts stronger effects in readiness/response than recovery/adaptability unless firms invest in partner data sharing and adaptive learning. Data–governance baselines, human–in–the–loop mechanisms and cross–functional interfaces help to test when and how AI yields durable performance effects. Conclusions. The application of AI within the different functional areas of the company is an irreversible phenomenon and will continue to be implemented. Indeed, it will become increasingly important. To gain insight into this phenomenon, an analysis of the current literature has been conducted, which has revealed that this is a world that is currently booming. This paper responds to the research question originally proposed. A comprehensive literature review has been conducted, both in the tables, figures and in the theoretical framework (RQ1). It is evident that this approach is being applied in several functional areas of the company. Furthermore, it has been possible to identify the areas in which the greatest efforts are currently being invested in its application, and a conceptual model has been created to help better understand this current application. The analysis of the different areas and the proposals made allows us to answer RQ2. It also provides the basis for a new theoretical framework, which can be further developed in subsequent studies by focusing on each of the functional areas discussed in this paper. The specific works that have been analysed in the different areas allow us to explore this issue in greater depth. In addition to identifying the relevant literature in Table 1, Table 2 analyses the journals with the greatest current impact in terms of the subject matter covered. Likewise, a conceptual model is proposed that can serve as a reference when implementing AI in different companies, depending on the functional area (RQ3). However, as can be seen, all of them seek greater efficiency within each functional area. Beyond mapping the present implementation of AI in organizations, the review identifies multiple thematic gaps that inform future research and theory development. From a functional perspective, the distribution of research remains uneven, with disproportionate attention being allocated to human resources and supply chain management in comparison to finance and marketing. In principle, the extant literature examines how AI is integrated into organizational processes or how it reshapes inter-functional coordination. Methodologically, the prevalence of qualitative and single-site case studies imposes limitations on the field’s ability to formulate cumulative or generalizable claims. It is recom-mended that future research endeavours seek to enhance the scope of empirical evidence, refine the theoretical models underpinning AI-driven organizational transformation, and adopt more diverse research methodologies, encompassing longitudinal and comparative approaches. Collectively, these gaps indicate that the organizational AI field is still in a formative phase, offering substantial opportunities for scholars to advance theory, inform managerial practice and shape the emerging research agenda. Theoretical and practical implications Beyond mapping how AI is currently implemented in organizations, the review identifies multiple thematic gaps that inform future research and theory development. Functionally, research remains unevenly distributed, with HR and supply chain receiving disproportionate attention compared to finance and marketing. Theoretically, limited work examines how AI is integrated into organizational processes or how it reshapes inter-functional coordination. This review offers several theoretical implications. Firstly, by synthesizing AI-related organizational transformations across strategic, functional, socio-technical and behavioural levels, the findings indicate that AI adoption constitutes a multilevel organizational phenomenon that cannot be adequately captured through single-level theoretical lenses. While individual-level perspectives such as TAM are valuable for explaining user acceptance, they are insufficient to account for the cross-functional coordination and capability reconfiguration processes identified in the literature. Secondly, the review highlights the need to integrate functional-level theories into contemporary discussions of AI in organizations, as functional domains constitute the locus of strategic execution and increasingly the domain in which cognitive and analytical tasks are redistributed by AI systems. Thirdly, the evidence suggests a theoretical bridge between Dynamic Capabilities, Information Processing perspectives, and Organizational Learning mechanisms through which AI-enabled capabilities become embedded and routinized. Together, these insights invite the development of integrative multilevel frameworks for theorizing AI in organizational contexts. This paper provides an overview of the current literature in the field of AI and its application in functional areas. The purpose of the conceptual model in this study is to structure and synthesize how AI is being implemented across organizational functional areas. Consequently, the proposed model aims to identify the key areas, mechanisms and propositions that future empirical studies could examine. Moreover, this can serve as a guide for organizations that are in transition to the new reality proposed by AI. Furthermore, this paper contributes to the existing literature by presenting a theoretical framework that not only outlines the current practices at the organizational level but also elucidates the underlying processes and the key considerations in the implementation of AI. The findings also generate managerial implications. The review suggests that the organizational benefits of AI are unlikely to materialize through technology acquisition alone. Instead, they are contingent on complementary organizational investments in cross-functional coordination, capability development and learning processes. Consequently, managers must regard the adoption of AI as an organizational design challenge, rather than a purely technical one. This necessitates the alignment of technological artefacts, structures, and human actors, consistent with socio-technical perspectives. In particular, the redistribution of analytical and cognitive tasks across functional areas implies a growing need for collaboration between technical and domain-specific units. In addition, the enabling role of AI in sensing and reconfiguring resources suggests that firms should develop adaptive capabilities that support iterative experimentation rather than one-off implementation decisions. These insights have the potential to assist organizations in expanding their AI initiatives beyond the pilot stage and towards the creation of sustainable value. The aim of this study is to provide valuable information for practitioners and organizations on how AI has been applied in departments. The objective is to analyse how AI is being implemented in each of the aforementioned departments. Furthermore, it identifies and prioritizes technologies for further development and proposes strategies for optimizing the deployment of these new tools in the business environment. The model provided can serve as a preliminary framework for decision-making, or as a basis for further analysis. The review offers several practical implications for organizations seeking to implement AI at scale. Firstly, the findings indicate that AI reshapes functional work by redistributing analytical and cognitive tasks. This, in turn, requires managers to reassess how expertise, decision rights and collaboration are structured across departments. This suggests that the adoption of AI should be regarded as a challenge to organizational design, rather than a decision that is purely technical in nature. Across the functional domains examined, the review shows that AI is predominantly leveraged to enhance analytical capabilities, automate routine processes, and support decision-making. In human resource management, AI supports talent acquisition, performance analysis and workforce planning, requiring managers to integrate algorithmic tools with sensitive evaluative processes and human judgement. In operations, AI contributes to forecasting, scheduling and process optimization, imply-ing the need for tight coupling between technical units and operational planners. In marketing, AI enables customer analytics and personalized targeting, which in turn requires the integration of data science capabilities with domain-specific market knowledge. In finance, AI supports risk mod-elling and financial forecasting, demanding close coordination between quantitative analysts, finance professionals, and IT infrastructure. Taken together, these patterns suggest that managers should facilitate cross-functional interfaces between technical and domain-specific experts in order to fully realize functional benefits. The results also imply that the adoption of AI operates across multiple levels of the organization. At the strategic level, AI supports sensing and reconfiguring resources, consistent with capability-building logics. At the functional level, AI alters coordination architectures by reallocating analytical tasks and reshaping workflows, requiring adjustments in roles, decision rights and collaboration structures. At the socio-technical level, effective implementation requires alignment between technological artefacts, organizational structures and human actors. At the individual level, the acceptance and utilization of these tools by employees are contingent upon their perceived usefulness and ease of use. It is therefore incumbent upon managers to pursue AI initiatives through a multilevel approach that integrates strategic intent, functional execution, socio-technical alignment, and behavioural acceptance. Managers should therefore design AI initiatives as organizational transformation processes that require complementary investments in coordination mechanisms, training, governance structures, and data capabilities. The framework developed in this review can serve as a preliminary decision-making tool for identifying where AI technologies may generate functional value, for prioritizing investments and for planning cross-functional integration. Limitations and future research lines To date, the most significant limitation has been the lack of specific literature. This is a very general and largely unspecific analysis, with little focus on each department. However, the human resources department does receive a more in-depth analysis, which is understandable given that the subject is relatively new, and the implementation of these tools in organizations has been occurring for a rela-tively short time. The exception to this is the DSSs, which have been within companies for more years. Conversely, it would be recommended to conduct further studies that are exclu-sively focused on each of the departments that are typically found within organizations. This would enable a more comprehensive and detailed analysis of the implementation of these new technologies, which are still emerging and developing over the next few years. Moreover, future studies could triangulate the conceptual model proposed here with a bibliometric co-word analysis to assess whether the thematic relationships identified by this review also emerge from the cognitive structure of the field. A further avenue for future study could be the utilization of alternative methodologies, such as the analysis of success stories, the administration of questionnaires, content analysis using Nvivo or atlas.ti, empirical analysis, and so forth. Another potential avenue for further research is the study of the implementation of AI in different sectors and companies, with a view to identifying similarities and differences. Given the considerable diversity of sectors and types of company, it is evident that the manner in which AI is implemented will vary considerably. For instance, a company specializing in tourism will implement AI in a very different way to another company in the automotive manufacturing sector. Ultimately, an additional avenue for future inquiry is the validation of the proposed model with a representative sample of firms in one or more sectors. This can be achieved through the use of Partial Least Squares Structural Equation Modeling (PLS-SEM) analysis, which will facilitate the testing of the model’s validity. Acknowledgements.
